WEIGHT AND PRESSURE RECORDING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 701,757, dated J une 3,1902.

Application tiled May 25,1901'. Serial No. 61,883. (No model.)

To all 1071/0711/ t may concern:

Beit known that I, EDWARDMCGARVEY, a citizen of the United States, and aresident of Bellefonte, in the county of Center and State ofPennsylvania, have invented a new and Improved l/Veight and PressureRecording Ap-v paratus, of which the followingis a full, clear, andexact description.

It is a recognized desire by scale` manufacturers and users to have anattachment by which the weight as indicated on the scalebeam may bequickly and accurately recorded on a suitable band or card in order toavoid mistakes liable to be made by the weighman in reading the weightfrom the beam and that the weighman may have a correct recordautomatically made to verify his weights in case ot dispute.

The object of my present invention is to provide a simple device thatmay be located at any desired distance from the scale by which weightsmay be recorded on an automatically-feeding strip of paper, thusobviating the placing of a card manually in recordreceiving position,and therefore causing a great saving of time.

Further objects will appear in the general description.

I willdescribea weight and pressure recording device embodying myinvention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, 'forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the Iigures.

Figure 1 is a side elevation of a recording apparatus embodying myinvention. Fig. 2 is a top plan View thereof, partly in section, ontheline to of Fig. Fig. 3 is a section on the line w w of Fig. 2. Fig. 4 isa section on the line 1/1/ of Fig. 3. Fig. 5 indicates upper and lowerscale-'beams with the circuitclosers thereon. Fig. 6 is .a section onthe line of Fig. 5. `Fig. 7 is a diagrammatic View illustrating thecircuits, and Fig. 8 is a detail view showing the iiexble wiresconnected to the poise.

The recording apparatus comprises a base 1, on uprights 2 of which areel 3 is mounted and from which a icing strip of record-paper is to bedrawn.`

The printing devices consist of two sets of peripherally-numbered disks,the two sets being-operated one independently of the other, one setbeing designed for coaction with circuit-closing devices carried by theupper scale beam, whereby weights to a certain amount may be printed,and the other series being designed for connection with circuitclosingdevices on the lower scale-beam to record the higher weights. The firstset comprises disks et, 5, and 6, mounted on a shaft 7, the units-disk4L being rigidly attached to the shaft, while the tens and hundredsdisks are loosely mounted on the shaft and operated from the units-diskin the usual manner. The other set comprises the numbered disks 8, 9,and 10, the units-disk 8 being rigidly attached to a shaft 11, while thetens and hundreds disks are mounted loosely on the shaft and operatedfrom the units-disk. The shafts 7 and 11 are supported from a cross-bar12, mounted on posts 13, extended upward from the base. The paper 11passes from the reel 3 underneath the printing-disks, and a stepby-stepmotion is imparted to the strip by means of a wheel 15, having teeth onits periphery to engage slightly into the paper, and the paper is heldyieldingly against ,the teeth by means of a roller 16, bearing upon theupper surface of the strip. This roller 16 has its shaft-bearings inarms 17, mounted to swing on posts 1S, and it is held downwardyieldingly by means of a spring 19, engaging at one end with one of thearms 17 and at the other end with a fixed portion of the machine, hereshown as a finger 20, extended outward from one of the posts or uprights18. Thefeed-Wheellislooselymounted on ashalt 2l, having bearings in theposts or uprights 18, and connected to this shaft is a ratchet-wheel 22and a pinion 23. The ratchet wheel 22 is engaged by a springpressed pawl24, mounted on the feed-wheel, and the pinion 23 is engaged by asegmental rack 25, pivotally connected to an angle-lever 26, onwhich ismounted an armature 27, coacting with an electromagnct 28. In theoperation of this feeding device when the elec= tromagnet 2S isenergized it will attract the armature 27, rocking the lever 26, andconsequentlymoving the rack 25,Which will cause a rotation of theratchet-wheel 22 for imparting motion to the feed-wheel 15. When theelectromagnet 28 is to be deenergized, a spring 29, connected at one endto the end of the rack and at the other end to a fixed portion of themachine, will draw said rack rearward, and as at this time the pawl 2stengages with a tooth ofthe ratchet-wheel the feed-wheel 15 will berotated a short distance to feed the paper strip. Arranged adjacent tothe printing-disks is a plate 30, upon which type are to be placed forprinting any desired matter-such, for instance, as the words Net, Gross,and No. The printing-surfaces of these letters on the plate 30 will ofcourse be in plane with the printing characters on the disks when suchcharacters are in printing position. The paper strip is pressed upagainst the type by means of a platen 3l, carried by an armaturelever32, which has connected to it an armature 33, coacting with anelectromagnet 3%. This armature-lever 32 is fulcrumed on screws 32bhaving bearings in posts 32u, and on the screws are lock-nuts 32C, and acurved spring 35 serves to compensate the change in magnetism of thearmature 33.

y Mounted to swing rearward of the printing devices is a frame 36, whichcarries an inking-roller 37 atthe forward ends of the lower arms 3S ofsaid frame, which are designed to move underneath the printing devices.The upper arms of this swinging frame and which are parallel with thelower arms 38 are connected to a shaft 39, having bearings in studs 40on the cross-bar l2. From an arm 4l, eX- tended outward from thear1nature-lever 32, a link 42 extends to a connection with the upperportion of the roller-carrying frame 3G. Therefore when the armature 33is attracted by the electromagnet 34 the platen 3l will be swung upwardto press the paper against the type; but before it reaches such positionthe frame 3G will be rocked to carry the inkingroller 37 over the typeand ink the same, and the frame will be prevented frommoving too farrearward by engaging with stop-arms #13. The journals of theinking-roller are seated in the forked ends etat of the lower members 38of the swinging frame and are held removably in such position by meansof springfingers 45. Therefore this roller may be readily removed whenit is desired to supply it with ink.

The first set of printing-disks are prevented from rotating too far bymeans of a springdog 4G, engaging with a notched wheel Li7 on the shaft7, while a similaidog 4S engages with a notched wheel 4-0 on the shaft11 to hold the shaft ll in its adjusted position. The lirst set ofprinting-disks are operated by an electromagnet 50, coacting with anarmature 5l on the lever 50 of which is carried a finger 52 for engagingwith the crown ratchet-teeth of either one of the wheels 53 or 5i,mounted on the shaft 7. The ratchetteeth of these wheels are in reverseorder, so that when the finger 52 engages with a tooth of the innerwheel 53 the printing-disks will be rotated in a forward direction; butwhen the said finger coacts with the ratchet-wheel 5ft the .disks willbe moved backward or in reverse order, as will hereinafter appear. Thewheels of the other series are operated by an eleetromagnet 55, coactingwith an armature 5G, to the lever 55L of which is attached a Iinger 57for coacting with either one of the crown-toothed ratchet-wheels 5S or59 on the shaft ll. The said teeth of the two ratchet-wheels are inreverse order, as described in reference to the wheels 53 and 54, andfor the same purpose, as will more fully appear hereinafter. The leverhas its shaft-bearings in screws 50h 50C, supported, respectively, by apost 32 and a post 50, and the lever 55 has its shaft-bearings in screws55b and 55C, supported in a post 32 and a post 55, and suitablelock-nuts are placed on these screws. The arm 60, on which the finger 52is mounted, is pivotally connected to the lever of the armature 5l, andthe arm 61, to which the finger 57 is connected, is pivoted to the leverof the armature 5G, and the two fingers 52 and 57 are connected by aspring G2, which has a tend ency to draw the fingers toward each other,but to hold them normally in operative position with relation to theinner ratchet-wheels 53 and 5S. The finger 52 has a spring-yieldingconnection ('53 with an arm 6i, which is connected to and extends upwardfrom an armature (55, coacting with what may be termed areversing-electromagnet Go'. The finger 57 of the arm Gl has aspring-yielding connection 67 with an upwardly-extended arm GS on thearmature 69 coactingr with a reversing-electromagnet 70.

I will now describe the circuit-closing devices designed to be attachedto the scalebeams and the electrical connections. It will be understoodthat especially in railwayscales the upper beam is provided withnotches. This upper beam isindieated at 7l, and the lower beam 72 isattached thereto. Mounted to move on the upper beam 7l to representweights up to a certain amount is a poise 73. Mounted on this poise 73is a circuit-closer comprising` a fingei-pressed arm 74, which is innormal electrical connection with the poise 73 through a loop 75, andthis arm 74 is designed to engage with a spring contact-finger 7G, alsocarried by the poise and insulated therefrom. Carried by one end of thepoise 73, but insulated therefrom, is an angular spring-yieldingcontact-finger 77, having aV-shaped end adapted to pass freely into anyone of the notches in the top of the beam, but to engage with the wallsthereof when the poise is moved along to close a circuit. Also carriedon the poise, but insulated therefrom, is a spring-yieldingcontact-finger 7 S, the lower end of which is provided with a IOC TIO

rubbercushion or tip 79, which bears upon the upper plain edge ofthebeam. This rubber tip is designed to produce a sufficient frictionbetween the parts, so that when the poise is moved reaward thespring-contact 7 8 will move into electrical connection with the poise.I have here shown a contact-lug SO on the poise adaptedto be engaged bysaid springflnger 78. Mounted to move along the lower beam 72 is a poise8l, which carries a contact-brush S2, engaging with the periphery of awheel 83, which has its periphery7 insulated at intervals, and atintervals contact-points are arranged for engaging with the brush S2. On`the shaft of this controlling-wheel S3 is a pinion 84, meshing withteeth S5, formed on the upper edge of the lower beam 72. From thecontact-spring 74 a wire S6 leads to one pole of a source ofelectricity, (here shown as a battery 87,) and from the other pole ofthis battery a wire 88 leads and has connection through a shunt 89 withthe electromagnet 50, from which a wire 90 leads to a connection withthe spring-finger 77. From the contact-finger 76 a wire 91 leads to thefeed-actuating electromagnet 28, and from this electromagnet 28 a wire92 leads to the electromagnet 34, from which a wire 93 leads to the wire8S, thence through the battery S7 and the wire S6 to the key orspring-arm 74. From the contact-finger 7S a wire 94E, provided with aresistance 95, this being a shuntwire, leads to one pole of theelectromagnet 66, while from the other pole a wire 96 leads to the wireS8, thence through the battery 87, the wire 86 to the poise, and back tothe spring-finger 7S when said spring-nger is in contact with the poise.From the contactbrush 82 a wire 97 leads to one pole of theelectromagnet 55, and from the other pole of this electromagnet a wire9S leads to a connection with the main wire S8, thence through thebattery S7, the wire S6, the poise 73, the two beams, and the poise 8lto the controlling-wheel S3. Carried by the poise Sl, butinsulatedtherefrom and adapted to be pressed into engagement therewith, is aspring-finger 99, from which a wire 100, which is a shuntwire, andtherefore provided with a resistance lOl, leads to one pole of theelectromagnet 70, while with the other pole the wire SS connects.Therefore when the linger 99 is moved in contact with the poise thecircuit will be closed through said finger 99, the wire 100, theelectromagnet 70, the wire 8S, the battery S7, the wire 86, and thencethrough the poises and beams back to the contact-finger 99 when inclosed position. As shown in Fig. S, the poises are electricallyconnected by very light flexible wires or cords to a block ofbinding-posts arranged at a point about equal distance from the two endsof the graduation, and the beam being once balanced with the wires nopractical error will be caused by the movement of the wires.

The operation is as follows: When the weight is on the scale, the poiseon the upper beam is to be moved along, and during this movement thecircuit will be alternately closed and opened by the contact 77 comingin engagement with the beam. When the circuit is thus closed, thecurrent will pass through the electromagnet 50, which by attracting itsarmature 5l will cause a step-bystep motion of the printing-wheels ofthe first series. Should the scale come to a balance by the poise on theupper beam, connection is to be made between the parts 74 and 76, whichwill cause a one-step movement of the feeding device and also actuatethe inkingroller and the platen in the manner before described. Shouldthe poise on the upper beam be moved too far forward, it will of coursemake it necessary to move it back. The spring-finger 7S will be bentinto engagement with the lug SO on the poise 73, and therefore thecircuit will be closed through the electromagnet 66, which by operatingits armature 65 will draw the finger 52 into operative connection withthe outer ratchetwheel 54, and the electromagnet 50 will operate torotate the numbered or printing disks in reverse direction. Should theweight on the scale be too great to be weighed by the poise on the upperbeam, the poise on the lower beam is to be moved along, and through theagency of the interrupted wheel 83 the circuit will be alternatelyclosed and opened through the electromagnet 55, which will operate thehigher series of printing-wheels. Should the poise on the lower beam bemoved too far forward, the weigher is to place his linger against thespring-contact 99, so that in pushing the poise rearward the said fingerwill come in electrical engagement therewith, thus closing the circuitthrough the reversingelectromagnet 50, drawing the finger 57 intooperative engagement with the ratchet-wheel 59 to reverse the movementof the printingwheels, and to close the feeding and platen operatingelectromagnets the key or arm 74 is to be engaged with the Iinger 76, asbefore described. It will be seen by this operation that the weightrepresented by the scale-beam will be accurately recorded by theinstrument.
